What are the causes of vibration in Rack & Pinion pneumatic actuators?

In the actual application process, Rack & Pinion  pneumatic actuators  may experience vibration, which is quite serious because vibration can cause the control system to malfunction. So, what is the reason for the vibration of Rack & Pinion Pneumatic Actuators?

1. External vibration source, that is, the equipment pipeline itself has vibration.

2. The selection of Pneumatic Actuator control valves does not meet the requirements of selection, such as unsuitable flow characteristics, oversized valve diameter, poor spring stiffness, etc., resulting in valve vibration

3. Vibration caused by fluid erosion

After reading the above content, I believe everyone already knows the cause of Rack & Pinion  pneumatic actuator  vibration.
